Give an example for alphs decay and write the range of Q-value for alpha decay.

Give an example for beta^+ - decay process.

Give an example for beta decay followed by gamma -decay (gamma decay).

During alpha -decay, n/p ratio :

IF {:|(sinalpha,cosbeta),(cos alpha,sin beta)|=1/2 , where alpha and beta are acute angles then write the value of alpha + beta.

Under certain circumstances, a nucleus can decay by emitting a particle more massive than an a-particle. Consider the following decay processes: ""_(88)^(223)Ra to ""(82)^(209)Pb + ""_(6)^(14)C . ""_(88)^(223)Ra to ""_(86)^(219)Rn + ""_(2)^(4)He Calculate the Q-values for these decays and determine that both are energetically allowed.

Give the expression for the range of the particle. For what value of angle of projection of the particle is the range maximum ?
