Abstract

A measurement of the energy differences of the

n = 2

,

{}^{3}P_{J}

states of charmonium may give significant information on the dynamics of the spin-dependent quark-antiquark (

q \bar{q}

) forces, since the more rapidly these forces increase with

q \bar{q}

separation, the larger the ratios

R_{1} = \frac{[E ({}^{3}P_{2}) - E ({}^{3}P_{1})]}{[E ({}^{3}P_{1}) - E ({}^{3}P_{0})]} and R_{2} = \frac{[E ({}^{3}P_{1}) - E ({}^{1}P_{1})]}{[E ({}^{3}P_{1}) - E ({}^{3}P_{0})]}

become if the forces are of vector character.
