Mod-01 Lec-24 Radioactivity, Alpha Decay

[@johnflorio3052]

Thank you, Professor! Much respect from the US.

[@RahulKumar-gc7lc]

He is one of the most loved Professors in India... Feeling much thankful to your comment Sir! Respect and love from India..❤

[@narasimhasithurea2271]

After listening to you I found nuclear physics is also as interesting as solid state 🙏

[@aniruddhavichare5425]

you make concepts look very simple and interesting.. Ur language is very lucid nd easy to grasp.. I have benefitted so much from your nuclear physics course

[@estefaniac7324]

Thank you so much! I'm sure you are helping a lot of people around the world, including me :)

[@abhayphysics01]

Our Professor is great🙏

[@nabinkarki6542]

brillaint as he is in his book

[@Himanshupandeypvt]

Best explanation ever 🔥🔥🔥

[@gauravshukla446]

really sir you have art of teaching science

[@ujjalkumardutta7777]

Thank you Sir, You are our proud

[@amitkumarshah7474]

At 10:23, I suppose it should be BE(aXz). Also the whole term should not be multiplied with c^2 when Q is equated in terms of BE.

[@subhajitdiasi3030]

Yes when B.E term is there c^2 is already multiple...

[@santanusingh4669]

Yes you correct

[@MdArman-pq2ik]

Proud to be a bihari,I'm from HC Verma Sir's city darbhanga bihar☺️☺️

[@anupambhattrai8174]

Haha..y u r proud if u belong to same city??

[@manishamishra7989]

Ab aap bhi padhkar professor bane

[@pannachetry7161]

i had one doubt at the last..but i think the potential barrier which u mentioned should be a nuclear potential barrier rather than coulomb barrier..correct me if i m wrong

[@sanketbhatt4097]

really sir I heard about ur experience which up to super

[@sourabhmaini1641]

35:00 Gammow Theory

[@jaiprakash3612]

Great lecture

[@NA-df4wh]

I like ur presentation

[@anandapatmanabhansu]

Thankyou sir❤

[@riturohilla8821]

Adbhud 🙏🙏🙏

[@krutikthakor4716]

For A greater than equal to 150 we get Q value positive but I can't understand that for 160 170 we may got some stable nuclei for which Q is negative can anyone explain me ?

[@anandapatmanabhansu]

Sir the alpha particle is in a repulsive potential, then how will it become a barrier for alpha particle

[@amaljeevk3950]

😍

[@jeevanshaili6958]

Enhanced speed 2x you will save time

[@swagatabanerjee_1038]

Thank you mam..... This really saves time...

[@deeptibhimavarapu5852]

hi sir u r really gr8 but i also want to translate ur lecturers somewhere in Hindi

[@ankitmishra2723]

Thanks sir

[@khanendrakumarraja4134]

Nice Lecture

[@mrpde1235]

how come proton change to neutron,law of conservation of mass is violate

[@chetan120]

as mass of neutron>mass of proton then in beta plus decay energy should be negative{[m(p)-m(n)-m(e)]×931.5MeV}, but in overall reaction we see that energy is releasing ,this energy comes from binding energy of nucleus{∆m=(∆E÷C^2)} thats why beta minus decay is more spontaneous than beta plus decay

[@Yadu_travel]

Very nice sir

[@pujagrover7591]

sir are these lectures for class 12th or for B-tech?

[@aozora_2k]

Not in 12th.... I am using in my B.Sc

[@gopiatluri2414]

sir ..plz tell me which book r u fallowed???

[@k.k.harjeeth5422]

@Varun Tripathi well said 👏

[@ankitsaha6718]

@Varun Tripathi kya yaar usko reference chahiye aru tu backchodi kaar raha ha..

[@hindicreations1075]

Wo khud book chapte h 😂

[@satyampanchal-1016]

Introductory nuclear physics by krane

[@meenakhemnanikhemnani2294]

sir can u explain me why half life is very important in nuclear physics why not full life time is there any reason behind this... Any one can ans

[@abhimanyusharma2185]

because technically they never decay completely, always some part even if minute remains . hence there is no full life .

[@manjeetchahal5548]

actually you can take anything other than full life which cannot be meaured

[@Anitabharga]

Full life of every neuclear reaction is always infinite

[@kiranwani4833]

Because theoretically total time required to decay any radioactive element is infinite..so it is not possible to use total life time of an radioactive element...so we use half life time..

[@efegokmen]

Brilliant

[@vijayprasad9725]

everything bounced off

[@fiercewolf7296]

U have to go and study the basics of physics

[@shailparmar3862]

Lecture me Hindi use karna chahiye

[@kushalpatel132]

why you think so?

[@suratsingh5029]

yes brother

[@phyvijay9]

Kyu karni chahiye .. If the course is in English the lecture should be in English, if the course is in Hindi it should be in Hindi. Why mix Hindi and English ...

[@pushkarkushwah2128]

easy to understand , so must had to use hindi here

[@aaqibali9349]

Strongly agreed
