Does a nucleus lose mass when it suffers gamma decay?

A radioactive nucleus X decay to a nucleus Y with a decay with a decay Concept lambda _(x) = 0.1s^(-1) , gamma further decay to a stable nucleus Z with a decay constant lambda_(y) = 1//30 s^(-1) initialy, there are only X nuclei and their number is N_(0) = 10^(20) . Set up the rate equations for the population of X , Y and Z The population of Y nucleus as a function of time is given by N_(y) (1) = N_(0) lambda_(x)l(lambda_(x) - lambda_(y))( (exp(- lambda_(y)t)) Find the time at which N_(y) is maximum and determine the populations X and Z at that instant.

When a nucleus with atomic number Z and mass number A undergoes a radioactive decay process, (i) Both Z and A will decrease, if the process is alpha decay (ii) Z will decrease but A will not change, if the process is beta^(+)- decay (iii) Z will increase but A will not change, if the process is beta^(-)- decay (iv) Z and A will remain uncharged, if the prices is gamma decay

Which of the following process represents a gamma- decay ?

For uranium nucleus how does its mass vary with volume?

A nucleus of mass M is initially at rest.It absorb neutron having m_(N) rest mass compound nucleus divided in two nucleus of m_(1) and 5 m_(1) .If wavelength of nucleus with mass m_(1) is lambda ,then wavelength of other nucleus will be…..

After absorbing a slowly moving neutrons of mass m_(N) (momentum ~0) a nucleus of mass M breaks into two nucleii of mass m_(1) and 5m_(1)(6m_(1)=M+m_(N)) , respectively . If the de-Broglie wavelength of the nucleus with mass m_(1) is lambda , then de Broglie wavelength of the other nucleus will be

Two objects of equal mass rest on the opposite pans of an arm balance. Does the scale remain balance when it is accelerated up or down in a life ?

A radioactive nuclide is produced at a constant rate x nuclei per second. During each decay, E_0 energy is released ,50% of this energy is utilised in melting ice at 0^@ C. Find mass of ice that will melt in one mean life. ( lambda =decay consant, L_f =Latent heat of fusion )

The unit of length conventent on the nuclear scale is a fermi : 1f = 10^(-15) m. Nuclear sized obey roughly the following empirical relation: r = r_(0)A^(1//3) Where r is the radius of the nucleus, A its mass number, and r_(0) is a constant equal to about, 1.2 f. Show that the rule implies that nuclear mass density is nearly constant for different nuclei. Estimate the mass density of sodium nucleus. Compare it with the average mass density of a sodium atom obtained in Exercise . 2.27.
