Exact calculation of the penetrability through triple hump fission barriers

Exact calculation of the penetrability of a triple hump potential barrier expressed by five smoothly joined parabolic functions is carried out by TCNT. Such a barrier defines the nuclear potential energy, as a function of the nuclear deformation which leads to fission, for certain isotopes of uranium and thorium. It can also represent the potential landscape defining two parts of the third fission potential barrier minimum which are separated in the direction of nuclear mass asymmetry. (orig.)
