Abstract

A good-resolution study of the reaction

{}^{42}{Ca} (p, t) {}^{40}{Ca}

has revealed the existence of three new

0^{+}

states in

{}^{40}{Ca}

at 7698, 8284, and 8438 keV excitation. Arguments are presented to show that these states are indeed the long sought-after

0^{+}

,

T = 0

states with predominantly two-particle, two-hole configurations.
