Abstract : Upper bounds on the strength of the average lambdanucleon interaction required to account for the observed binding of the hypertriton have been established in a variation calculation with a tenparameter trial function. Central twobody potentials having hardcore radii 0.2, 0.4, and 0.6 F and ranges suggested by consideration of the twopionexchange mechanism were used. These calculations led to improvements of 36% (depending upon the hardcore radius) in the required strengths over the results of previous calculations with a fourparameter function. The results cannot be used to rule out the existence of a bound hyperdeuteron of spin 0 for a hardcore radius as large as 0.6 F. A partial variation calculation is described, in which only two of the ten parameters of the trial function are varied. When the remaining parameters are fixed by consideration of the twobody subsystems of which the hypertriton is composed, variation of two appropriate parameters leads to required strengths within 3% of the values obtained by varying all ten parameters.
